2003 GMC Sierra Trucks Factory Recalls


General Motors vendors issued 11 recalls, mostly for minor problems, between 2003 and 2009 for the model year 2003 Sierra pickup truck. Five recalls involved aftermarket parts installed on 2003 GMC trucks between 2004 and 2009. Some factory parts defects were not detected until after the trucks were sold and had been driven over time.

Aftermarket Recalls

  • In 2009, GM issued recall notices for 42,540 model year 2003 GMC Sierras due to a faulty aftermarket exterior light part sold by Dope, Inc. The part was the corner bumper lamp assembly. It failed to adhere to federal safety standards because the assemblies do not contain amber reflectors. Dope offered refunds. In 2007, GM issued recall notices due to a defective aftermarket wiring harness for fifth-wheel RV trailer lights. The faulty harness could cause the trailer lights to fail and pose a safety risk.

Fuel System

  • In 2006, more than 88,000 model year 2003 GMC Sierra 1500 trucks received recall notices for a fuel filter that had an improperly seated O-ring that could leak and cause a fire. The fuel filter was a replacement part from Honeywell International and sold in 2005 and 2006 for 2003 GMC trucks and school bus engines. The fuel filter did not adhere to safety specifications. Honeywell replaced the filters.


  • GM issued a recall in 2005 for an estimated 90,242 model year 2003 GMC Sierras equipped with manual transmissions and PBR or TRW brake systems because the parking brake could fail due to extensive wear. GM repaired the parking brake. Also in 2005, GM recalled 68,875 model year 2003 GMC Sierras because the braking system's hydraulic boost housing relief valve did not meet federal safety specifications. The fault could lead to an O-ring failing, with steering becoming more difficult as brake pressure is applied. GMC dealers replaced the relief valve.

Seat Belts

  • In 2004, an estimated 736 regular and extended cab 2003 GMC trucks received recall notices because the front passenger child restraint anchor only featured one position when the standard is to have two anchor positions. The position of the seat is not appropriate in case the airbag deploys. GM made alternations to prevent the airbag from incorrectly activating on the regular cab pickups and changed the front passenger seat on extended cab models. In 2005, more than 1.36 million GM vehicles, including 2003 GMC Sierra crew cab models, were recalled due to rear seatbelts that were loose and did not restrain small occupants. GM corrected the problem.

Body and Wheels

  • About 366,000 model year 2003 GM vehicles, including GMC Sierras, received recall notices in 2004 for faulty tailgate support cables that could break. In 2007, recalls were issued for faulty wheel hub assemblies that could fall off on 130,000 GM vehicles, including 2003 Sierra 1500s. Windshields failing to conform to federal safety standards on 110 model year 2003 Sierras resulted in a 2003 recall to be replaced. In 2004, GM recalled 8,000 model year 2003 Sierras because a faulty toggle wing securing the bedliner to the cargo box could lead the bedliner to detach. Aftermarket supplier Durakon repaired or replaced the bedliner.
